Two questions.
a) there's no '_attachments' in the URL is there ? - it's working for
me without the _attachments but not with.
b) this is what I was doing before I tried to make it work with the file://
But not using a callback=? param and using the following url - just to
see if I can get any json at all -
$.get("http://localhost:5984/", function(data){ alert(data); } );
gives me an alert with nothing in it.
